Mark S. asks: Why does brown sugar form lumps but regular sugar doesn’t?

But why? The idea for designating different storage devices with simple letters is generally attributed to […]

Rita H. asks: Why do we serve ham on Easter? Under Jewish dietary laws (called kashrut), eating pork in any form is strictly forbidden. Jesus Christ was Jewish.

Lindsey asks: How fast do electrons flow inside electrical cables? You may be surprised to learn that electrons flow through a typical copper wire much slower than a turtle walks. Each wire that conducts a flow of electrons, producing usable electric current, is composed of billions of atoms. To move along it, the electrons have to traverse these atoms, randomly […]

Byron H. asks: When exactly does a speed limit come into effect? Is it when you see the sign or the instant you cross it? If it’s an increase in speed can you legally accelerate up to the speed so your speed matches the sign right when you get to it, or do you have to wait? On paper, speed […]

Nick C. asks: How did they settle on six feet deep for graves? If there’s one thing everyone knows about graves other than the fact that they’re really spooky at night, it’s that they’re always six feet deep.

Bon-hwa S. asks: Worms drown in the water, so how do fish know they are food? Is the reason they like them just the movement? Thanks! Worms, or more specifically earthworms which are by far what most people mean when they use the term “worms” in the fishing scenario, don’t live in water. In fact, the reason you see so many on […]

Erin G. asks: Why do we color code electric wires the way we do? Black, white, green, red, blue, orange, brown and grey, the color of the insulating sheath on an electrical wire generally designates its purpose. So, before you start fiddling around with that new light fixture, besides switching off the breaker to a given circuit, it’s a good […]

Jim asks: Do non-human animals ever get sunburned? Why don’t things like snakes and other cold blooded animals seem to get burned even though they lay in the sun all day?
